curl -s https://whosthatbot.com/v1/crawlers/yandexblogs

Check this token

tools/call with name check_robots is the same check at POST /mcp. The pasted file disallows YandexBlogs on /docs and allows *. The call does not fetch a host.

curl -s https://whosthatbot.com/mcp -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"check_robots","arguments":{"robots_txt":"User-agent: YandexBlogs\nDisallow: /\n\nUser-agent: *\nAllow: /\n","path":"/docs","ids":["yandexblogs"]}}}'

That call returns fetched_target false. This row is disallow via group YandexBlogs, rule Disallow: /.
